    摘要: A pipe-in-pipe assembly with thermally-insulating spacers positioned in an annulus to act radially between inner and outer pipes is disclosed. The spacers have at least one circumferentially-extending array of circumferentially-spaced ribs that define longitudinally-extending passageways in gaps between neighbouring ribs of the array. Cables including heating elements extend longitudinally along the annulus outside the inner pipe. The cables extend longitudinally along the passageways. At least one insulation layer disposed radially outboard of the cables has insulating elements disposed in the gaps between the ribs and/or an insulating layer extending around the inner pipe, positioned radially outboard of the ribs and bridging the gaps. Bands encircle and retain components of the insulation layer. Insulation may also be disposed on the inner pipe between first and second arrays of ribs, those arrays being spaced longitudinally from each other.

    摘要: A system for transferring and heating fluid is disclosed comprising a fluid transfer pipe having an internal surface and an external surface, and at least one helical heating rib connected to the internal surface of the fluid transfer pipe structured and arranged to generate non-laminar flow and to heat the fluid as it flows through the fluid transfer pipe. A method of heating fluid contained in a pipe is also disclosed. The method comprises providing at least one helical heating rib connected to an internal surface of a fluid transfer pipe, and passing the fluid through the fluid transfer pipe, whereby the at least one helical heating rib generates turbulent flow of the fluid to thereby heat the fluid. The helical heating ribs may comprise hollow channels through which a heating liquid may be passed to further heat the fluid contained in the pipe.

    摘要: A fluid conduit that is below grade or under water is separated from ambient water by a confined layer of liquid that may be largely undivided by solids. The separation distance between the liquid containment means and the piping or pipeline is such that the total heat transfer by natural convection and conduction from the piping or pipeline to the water containing environment is kept within limits thought necessary to adequately insulate the contents of the pipeline. A liquid may be pumped between the pipe and the means for containing the insulation so as to displace fluids from a pipeline or a heated liquid may be pumped through that space to warm the contents of the pipeline. If the insulating liquid also electrically insulates the pipe, then the pipe may be heated by passing a current directly through the pipe.

    摘要: Within examples, a method of manufacturing a double-walled titanium conduit is described. Example methods include stitch welding multiple concentric sheets to form a stitch layer, providing the stitch layer between an inner wall and an outer wall of the double-walled titanium conduit, circumferentially seam welding the inner wall and the outer wall to the stitch layer to create a welded assembly, die forming the welded assembly at temperature and pressure to form inner structures between the multiple concentric sheets according to stitch welding lines and to enable a diffusion bond process among the inner wall, the stitch layer, and the outer wall, and removing the double-walled titanium conduit from the die.

    摘要: High flow capacity corrugated coilable dual wall plastic pipe having improved longitudinal flexibility and a bend radius sufficient to permit coiling and plowing of such pipe into the ground using automated installation equipment. The coilable dual wall pipe has an outer corrugated wall formed of a thermoplastic material such as high density polyethylene, and an inner smooth wall formed of a different more flexible and resilient thermo-bondable material that has an enhanced strain capacity and lower modulus of elasticity. The inner wall material also has enhanced mechanical properties which generally improve processing and help prevent excessive drag and tearing of the liner material during the manufacturing process. Suitable material blends for the inner wall in corporating a thermoplastic elastomer additive in combination with a thermoplastic material have proven suitable in providing the required longitudinal flexibility and pipe bend radius to permit the desired pipe coiling and plow installation without failure.
